MALCOLM L. COSSITT, OF ALAMEDA, CALIFORNIA, ASSIGNOR T0 MANIFOLD IMPRESSIONS CORPORATION, OF CA 031 NEVADA.

RSON CITY, NEVADA, A CORPORATION MANIFOLDING ATTACHMENT FOR TYPE-WRITERS.

Application filed December 27, 1921. Serial No. 524,880.

To all whom it nmy concern:

Be it known that I, MALCOLM L. Cossrr'r, a citizen of the United States, residing at Alameda, in the county of Alameda and State of California, have invented certain new and useful Improvements in Manifolding Attachments for Typewriters, of which the following is a specification.

My invention relates to the class of attachments to typewriters and similar typeimpact machines in which plural record sheets are entered, held, and guided in spaced relation about the platen, and pass on each side of a manifolding member,

' whereby an original and a carbon copy may be produced.

The object of my invention is to provide simple and practical means for entering, holding and guiding in spaced relation and in association with the platen, plural record sheets, and for disposing between them at one portion of their forward feed, a manifolding sheet, adapted for presentation together with said record sheets in the line of type impact, whereby plural records may e ma e.

To this end my invention consists in the novel manifolding attachment which I shall hereinafter fully describe by reference to the accompanying drawings, in which- Fig. 1 is an end view and part section of rIr y attachment taken'on the line 1-1 of Fig. 2 is a cross section on the line 2-2 of Fig. 3.

Fig. 3 is a front-elevation, broken, and partly in section of my attachment.

Fig. 4 is a front view of the innermost guide apron, the platen being omitted.

ig- 5 is a sectional detail enlarged, showing the container and the fan-folded manifolding sheet therein.

ig. 6 is a similar sectional detail, showing the manifolding sheet in the form of a roll, instead of fanfolded.

1 indicates a part of the platen-carriage of a t pewriter, and 2 is the platen having a shaft 3 and thumb wheel 3, by which it is turned for line spacing and feeding the record sheets asusual.

4. is an outer guide-apron carried by the platen carriage. and extending from a line back. of the platen, downwardly to and under said platen. The apron 4 is apertured along its rear portion as shown at 4, In Fig. 2, and through these apertures play the presser-rollers 5 which are carried by a shaft 6 mounted on the platen-carriage. 7 1s a second apron which serves both as a record sheet guide and separator and as a carrier for the manifolding sheet. This apron is pivotally supported on a rod 7" of the platen carriage and extends thence under the platen. It lies between the platen and the first apron 4 and is spaced from both. It is apertured as shown at 7, in Fig. 2, its apertures registering with those of the apron 4, so that the presser-rollers 5 play through both sets of apertures. There may be one or more such aprons as 7. I have here shown two. The upper back portions of the apron 4 and the aprons 7 relatively diverge or flare as shown in Figs. 1 and 2 to afford convenience and accuracy in entering the record sheets as will be presently described. The aprons 7 terminate below the line of type impact, which line is indicated by the tvpe 8, the index pointer 9, and the main inking ribbon 10 of the machine, as shown in Fig. 2.

The lower or ,free extremity of each apron 7 carries the manifoldin'g sheet 11. This sheet may be of any suitable nature, preferably what is known as carbon paper, but instead of being inthe form of relatively short separate sheets it is best a long strip or web having a width about equal to that of the record sheets. It may be carried by the aprons 7 in various ways, forexample, as shown in Figs. 2 and 5, wherein it lies fan-folded in a container 12, formed in or on the lower end of the apron 7, said container having an exit opening 12 and a hinged cover 12", Fig. 5; or it may be carried as a roll 13 in the container or the apron 7 as shown in Fig. 6.

Upon the upper front of the platen-carriage, above the line of type-impact, I have shown impinging feed rolls v14 adapted to be operated by suitable means, as by the thumb-wheels 14', Fig. 3, to feed the carbon sheets forward.

15, in Fig. 2, indicates, in dotted lines, the record sheets of aper, there being three here shown, one or the original and two for the duplicates. These three record sheets are inserted in the flaring entrances between the apron 4; and the two aprons 7.

The outermost or original record sheet enters between the apron 4 and the outer one of the two aprons 7. The first duplicate record sheet enters between the two aprons 7, while the second duplicate record sheet enters between the inner apron 7 and the platen. When the platen is turned on its axis, the presser rollers 55, protruding through the apertures of the aprons 4E and 7 press all three record sheets against the platen, so that the rotation of the latter feeds the sheets forward, past the extremities of the aprons 7, and up around the face of the platen behind the index pointer and main inking ribbon to and beyond the line of type-impact.

The two carbon sheets 1l having been drawnout in part from their containers and passed up between their feed rolls 14, lie between the original record sheet and between the two duplicate record sheets, respectively, as seen in Fig. 2, and as all sheets, both record and carbon, are thus presented in proper relative position in the line of type impact, an original and two copies of the record will be made.

In line spacing only the record sheets will be fed forward, the carbon sheets remaining stationary, but as occasion requires, said carbon sheets may be drawn forward sufficiently to present fresh surfaces in the line of type impact, by manipulating the feed rolls 14.

In order to conveniently replenish the store of carbon-paper, I mount the platen 2 upon arms 16 having a pivotal center at 1:? on the platen carriage. The platen can tnus be swung up, as shown by the dotted lines in Fig. 2, in order to expose the innermost carbon container; and the apron 7 which carries this container may also be swung up about its rod at 7", to expose the next container.

I claim 1. A manifolding attachment for typewriters, comprising an apron carried by the platen-carriage of the machine, and associated with the laten thereof to receive a record sheet and guide it in its forward feed; a second apron carried by the platen-carriage in spaced relation to the first apron, to receive and guide a second record sheet and separate it from the first record sheet; and a manifolding sheet connected with the second apron and adapted to lie between the two record sheets.

2. A manifolding attachment for typewriters, comprising an apron carried by the platen-carriage of the machine, and associated with the platen thereof to receive a record sheet and guide it in its forward feed; a second apron carried by the platen-cari'iage in spaced relation to the first apron, to receive and guide a second record sheet and separate it from the first record sheet; and a manifolding sheet stored upon the second apron and adapted to be drawn therefrom as required to lie between the two record sheets.

3. A manifolding attachment for type writers, comprising an apron carried by the platen-carriage of the machine, and associated with the platen thereof to receive a record sheet and guide it in its, forward feed; a second apron carried by the platencarriage in spaced relation to the first apron, to receive and guide a second record sheet and separate it from the first record sheet; a container carried by said second apron: and a manifolding sheet fan-folded in said container and adapted to be drawn therefrom as required, to lie between the two record sheets. 7

4.
